How to make 1N and 1M H2SO4 ?

Now let's see how to make 1 N and 1M  H2SO4 from 98% concentrated H2SO4 . This calculation varies with concentration of H2SO4. Because density varies with concentration of H2SO4 . Now we are having density 1.84 for 98% concentrated H2SO4.  If you are going to use less concentrated H2SO4 then first find out density of it then put that value in below formula instead of 1.84 H2SO4 is liquid, so at first we need to convert H2SO4 molecular weight (gm) into volume (ml) let's use formula density = mass / volume volume = mass of HCl  / density                             98.08 / 1.84 V = 53.30 ml Here we are making 1M and 1N  H2SO4 from 98% concentrated H2SO4. If you are going to use less concentrated H2SO4 then use that percentage value in below formula rather than 98%. Let's use formula  1M H2SO4 (98%) =  53.30 ml [ V ]                100%    ...

Omicron new variant of covid-19.

 After  alpha , beta, gamma , and  delta plus  variant of covid-19 the new variant of covid-19  omicron  has came in market and has already started to spread all over the world.  Origin of omicron :   According to recent information County  Botswana  of the South Africa was place place where first case of omicron found. But it's not true actually south Africa was the one who informed all world about new variant omicron. That was south africa goodness.  After all this time, now know we know where omicron really came from. Now Netherland, Belgium and Germany revealed that omicron was already present in our country's before south Africa. According to Netherlands on November 19th they took some samples from Corona affected people and that's when they realized there is new variant of covid-19 and now they have announced  lockdown  in Netherland. In Netherland theaters, Bar, restaurants, will be close after 5 o.clock . That's me...

which is best covaxin or covishield

   Currently there are just two vaccines are available in India Covishield and covaxin. Covaxin is fully india made vaccine by bharat biotech, and covishield is indian made version of astrazeneca's vaxzevria jab which has been manufacturing by pune based serum Institute of india. How they are made?  Covaxin is inactivated vaccine which has been prepared on trial and tested platform of Dead viruses. This vaccine is based on whole virion inactivated vector cell derived technology . It contain inactivated viruses, despite that it doesn't affects person. Instead of that it teach  human imune system to create a defence mechanism against active viruses.  Covishield has been prepared by using viral vector platform which is completely different from the covaccine technology.  Chimpanzees adenovirus has been modified to carry covid-19 spike protein into human body cells This cold virus is unable to affect human body but it can teach to our human system to create ant...
